Warning regarding not using bundler when running guard init

In my Rails app am getting this warning when running

guard init rspec

:

Warning: you have a Gemfile, but you're not using bundler or
RUBYGEMS_GEMDEPS
14:54:15 - INFO - Writing new Guardfile to
/home/ubuntu/railsprojects/sillyfish/Guardfile 14:54:16 - INFO - rspec
guard added to Guardfile, feel free to edit it

I don't understand why it's showing. Is it okay to ignore this warning?

If you run guard init rspec, it will use the globally installed guard-rails. To run the one installed through your Gemfile, use bundle exec guard init rspec. This is also what is recommended in the documentation.

From the README:

It's important that you always run Guard through Bundler to avoid errors.

So it's probably best to take this warning seriously, to avoid issues down the line.
